下载到板子上编译是可以的,你这个编译linva的没有问题的。但是你们没有libva的driver。所以libva加载不了 ...
十分感谢,因为我安装的是ubuntu16.04的系统, 使用bbs上发布的系统版本:ubuntu_1604_2016_10181213,上面已经有你的测试的例子test_dec.sh和test_enc.sh.,我想着上面已经有针对rk的libva的driver了,是不是已经有了啊?gstreamer进行测试的时候,可以进行硬件解码的。
并且增加了环境变量export LIBVA_DRIVER_NAME=rockchip
之后运行仍然不行!
如果需要安装rk的libva的driver有网址或者参考资料可以提供一下吗?谢谢 如果是官方的固件,libva和driver都已经有了的啊。
rockchip的libva的driver在这里 https://github.com/rockchip-linux/rockchip-va-driver 编译:https://github.com/rockchip-linux/rockchip-va-driver
rockchip_driver.h:147:2: error: unknown type name ‘VABufferInfo’
有人遇到这个问题吗? isle 版主,https://github.com/rockchip-linux/rockchip-va-driver下载后在rk3288里cmake少了libva库
CMake Error at CMakeLists.txt:15 (message):
failed to find libva (VA-API Library) isle 版主,在ubuntu16.04固件,在/usr/local/bin/test_dec.sh用gsteamer解码播放1080p ok,硬件调用/usr/lib/arm-linux-gnueabihf/dri/rockchip_drv_video.so;
用https://github.com/01org/libva-utils的vainfo demo查看,testdemo测试,va_getDriverName()返回-1,调用/usr/lib/arm-linux-gnueabihf/dri/rockchip_drv_video.so,但硬解码失败;
这是什么原因了?
